Locally however it is save, alt-tab, ctrl-r and immediately you see the result. Absolutely no waiting.
These days I rather use Quarkus for this but until Quarkus arrived this was a huge advantage that PHP had over every other language and framework I was aware of.
Also the documentation was fantastic compared to most of the stuff I have had to suffer through on Java, .Net and even React and Angular.
Every thing you may reasonably wonder about was described in a clear, straight forward way and included examples.
